STARS: 4 out of 5
TAYLOR FORK BOONDOCKING, GALLATIN NATIONAL FOREST, MONTANA (NEAR WEST YELLOWSTONE AND BIG SKY): GPS 45.0638° N, 111.2911° W
This is a great boondocking spot for access to Yellowstone (via the west entrance) and to Big Sky. It has ample options and seems to be known by locals, but not many others.
There were spots along the Gallatin river, and others on the opposite side of the road. There is a map available showing all the spots:
This document will help guide you to your preferred spot, so download it before you go. The numbers on the camping spots refer to mile markers. We stayed in 3.9 Lower Wapiti. This is by far the largest and easiest of all of the spots, and is perfect for trailers, fifth wheels, new drivers, etc. The bonus to this spot is a drop toilet on the campsite.
I've posted here a ton of photos of many of the different sites. If you are in a small RV (a class B, B+, small C or A, or a camper van) I personally would go down past the five mile marker for some of the more private spots. But if you are in a larger trailer, fifth wheel, or just a larger RV, I'd hang out at the 3.9 mile marker. If you go down there and that spot is taken, you can go down to the 5.8 Meadow spot which is also a big circle and easy to navigate. The downside to any spot past 3.9 is that there is a fairly narrow (but short) bridge that you have to go across (photo in the gallery on the left).
We would have given this even more stars if the easy site had been riverfront. It is one of our favorite sites that we've stayed in though. And we saw tons of grizzlies! Check out our videos on our blog.
If you want to drop a vehicle (tow or trailer) and explore, there are a ton of turn-outs on highway 191, including a pull-out right after the Yellowstone entrance on 191 (near mile marker 25 on 191).
NOTE: the GPS coordinates are to the Nine Quarter Circle lodge that is at mile marker 5 on Taylor Fork Road. There is NO cell reception out there, so I couldn't get coordinates at the individual sites.
